HTML_Quickform

Hi folks, I've used the HTML_Quickform package to display some forms. To have a flexible design, I used the Quickhtml renderer: $this->renderer =& new HTML_QuickForm_Renderer_QuickHtml(); $this->addElement('text', 'zone', "Zone: ", array('class' => 'field', 'size' => 50, 'maxlength' => 255, 'value' => $post->getRaw('zone'))); . . . $this->addRule('zone', 'errormessage', 'required', null, 'server'); $this->accept($this->renderer); The form is displayed quite fine, but no error message is vissible after committing the form in a invalid state. The client-side validation works fine, but the error text ($this->setJsWarnings("pretext", "posttext");) is not changeable... Whats the correct way to get the error message from the form object, and how can I display it in my html template? I can't find a method to extract the error message from the form object! How can I change the js-popup text? $this->setJsWarnings("pretext", "posttext"); has no effect (but also occures no error)... Thanks a lot Patrick
